RESUMEN

BACKGROUND: Perceived weight discrimination is associated with increased risk for chronic diseases and reduced life expectancy. Nevertheless, little is known about perceived weight discrimination in racial, ethnic, and sexual minority groups or in individuals at the intersections of those groups. The goal of this study was to identify sociodemographic predictors of perceived weight discrimination. SUBJECTS/METHODS: A diverse sample of adults (37% Black/African American, 36% Latino, 29% sexual minority) with a body mass index (BMI) ≥ 18.5 kg/m2 were recruited from a national US panel to complete an online survey (N = 2454). Perceived weight discrimination was assessed with the Stigmatizing Situations Survey-Brief (SSI-B). Using hierarchical linear regression analysis, SSI-B scores were predicted from the four sociodemographic characteristics of interest (gender, race, ethnicity, and sexual orientation) while controlling for BMI, age, education, and income (Step 1). At Step 2, all two-way interactions between the four sociodemographic characteristics were added to the model. RESULTS: At Step 1, higher SSI-B scores were observed for Latino (vs. non-Latino) adults, sexual minority (vs. heterosexual) adults, younger (vs. older) adults, adults with higher (vs. lower) levels of education, and adults with higher (vs. lower) BMI. At Step 2, race interacted with gender, ethnicity, and sexual orientation to predict SSI-B scores such that relatively higher scores were observed for non-Black women, Black men, adults who identified as Black and Latino, and non-Black sexual minority adults. CONCLUSIONS: Perceived weight discrimination varied across sociodemographic groups, with some subgroups reporting relatively high frequency. Black race appeared to be protective for some subgroups (e.g., Black women), but risk-enhancing for others (e.g., Black men, individuals who identified as Black and Latino). Additional research is needed to identify specific factors that cause certain sociodemographic groups -and indeed, certain individuals-to perceive higher levels of weight discrimination than others.

RESUMEN

Abortion policy is conventionally viewed as a political matter with religious overtones. This article offers a different view. From the perspective of evolutionary biology, abortion at a young age can represent prioritization of long-term development over immediate reproduction, a pattern established in other animal species as resulting from stable ecologies with low mortality risk. We examine whether laws and moral beliefs about abortions are linked to local mortality rates. Data from 50 U.S. states, 202 world societies, 2,596 adult individuals in 363 U.S. counties, and 147,260 respondents across the globe suggest that lower levels of mortality risk are associated with more permissive laws and attitudes toward abortion. Those associations were observed when we controlled for religiosity, political ideology, wealth, education, and industrialization. Integrating evolutionary and cultural perspectives offers an explanation as to why moral beliefs and legal norms about reproduction may be sensitive to levels of ecological adversity.

RESUMEN

BACKGROUND: Human reproductive dynamics in the post-industrial world are typically explained by economic, technological, and social factors including the prevalence of contraception and increasing numbers of women in higher education and the workforce. These factors have been targeted by multiple world governments as part of family policies, yet those policies have had limited success. The current work adopts a life history perspective from evolutionary biology: like most species, human populations may respond to safer environments marked by lower morbidity and mortality by slowing their reproduction and reducing their number of offspring. We test this association on three levels of analysis using global, local, and individual data from publicly available databases. RESULTS: Data from over 200 world nations, 3,000 U.S. counties and 2,800 individuals confirm an association between human reproductive outcomes and local mortality risk. Lower local mortality risk predicts "slower" reproduction in humans (lower adolescent fertility, lower total fertility rates, later age of childbearing) on all levels of analyses, even while controlling for socioeconomic variables (female employment, education, contraception). CONCLUSIONS: The association between extrinsic mortality risk and reproductive outcomes, suggested by life history theory and previously supported by both animal and human data, is now supported by novel evidence in humans. Social and health policies governing human reproduction, whether they seek to boost or constrain fertility, may benefit from incorporating a focus on mortality risk.

RESUMEN

OBJECTIVE: Spiteful behaviors are those aimed at inflicting harm on another person while also incurring a cost to the self. Although spite sometimes reflects destructive and socially undesirable behaviors including aggression, the current work sought to examine a potentially socially beneficial aspect of spite: engagement in costly punishment for selfish behavior. METHOD: Four studies used a costly third-party punishment task and measured individual differences in spite, narcissism, Machiavellianism, psychopathy, and motivations for engaging in punishment. RESULTS: Trait spite was positively associated with costly punishment of selfish behavior. That association was independent of other dark personality traits (narcissism, Machiavellianism, psychopathy) and was statistically mediated by a desire for retribution. One of the studies also provided evidence that trait spite was associated with costly punishment of even generous behavior; however, rather than a desire for retribution, that association was mediated by a desire to threaten the person being punished. CONCLUSION: Punishing selfishness and other forms of wrongdoing plays an essential role in cooperative group living. The current work provides new insight into the role spiteful motivations might play in this crucial social behavior.

RESUMEN

A correlational pilot study (N = 143) and an integrative data analysis of two experiments (total N = 377) provide evidence linking anger to the psychology of social hierarchy. The experiments demonstrate that the experience of anger increases the psychological accessibility of implicit cognitions related to social hierarchy: compared to participants in a control condition, participants in an anger-priming condition completed word stems with significantly more hierarchy-related words. We found little support for sex differences in the effect of anger on implicit hierarchy-related cognition; effects were equivalent across male and female participants. Findings fit with functionalist evolutionary views of anger suggesting that anger may motivate the use of dominance to strive for high social rank in group hierarchies. Implications for downstream behaviour, including aggression and negotiation, are discussed.

RESUMEN

BACKGROUND: People with obesity face significant discrimination due to their weight. Exposure to such discrimination is associated with poor health outcomes. Little is known about pathways that explain that association, and even less is known about those pathways in racial, ethnic, and sexual minorities. Health risk behaviors may serve as one such pathway. PURPOSE: We examined associations between weight discrimination and health risk behaviors and assessed whether associations are moderated by gender, race, ethnicity, or sexual orientation. METHODS: Quota sampling was used to oversample Black (36%), Latino (36%), and sexual minority (29%) adults (n = 2,632) who completed an online survey. Using regression analysis, health risk behaviors (maladaptive eating behaviors, physical inactivity, sitting, smoking, alcohol use, and sleep disturbance) were predicted from previous experience with weight discrimination while controlling for demographic characteristics, BMI, and depressive symptoms. Additional analyses tested for interactions between weight discrimination and key demographic variables (i.e., gender, race, ethnicity, and sexual minority status). RESULTS: Weight discrimination was associated with greater emotional eating, binge eating, unhealthy weight control behaviors, cigarette smoking, problematic alcohol use, and sleep disturbance. Gender moderated the association between weight discrimination and binge eating, alcohol use, and physical activity, with stronger effects observed in men than women. Exploratory analyses provided limited evidence for differential effects of weight discrimination across specific combinations of intersecting identities. CONCLUSIONS: Weight discrimination was associated with engagement in unhealthy behaviors and relationships were largely similar across diverse demographic groups. Health risk behaviors may represent a key pathway through which weight discrimination harms health.


People with high body weight remain one of the most stigmatized groups in the USA and face significant discrimination due to their weight. Experiencing weight discrimination is associated with poor health, yet little is known about the underlying pathways that explain this association and even less is known about those pathways in socially marginalized groups. We investigated unhealthy behavior as a possible a pathway by assessing associations between weight discrimination and several health risk behaviors and identifying whether those associations vary by gender, race, ethnicity, or sexual orientation. A diverse sample of 2,632 U.S. adults completed an online survey. Previous experience with weight discrimination was found to be associated with greater emotional eating, binge eating, unhealthy weight control behaviors, cigarette smoking, problematic alcohol use, and poor sleep. The association between weight discrimination and binge eating, alcohol use, and physical activity was stronger in men than in women, yet exploratory analyses provided limited evidence for differential effects of weight discrimination across specific combinations of intersecting identities. Weight discrimination was associated with engagement in unhealthy behaviors and associations were largely similar across participants from diverse demographic groups. Health risk behaviors may represent a key pathway through which weight discrimination harms health.

RESUMEN

The current investigation examined whether women's perceptions of the sex ratio (ratio of women to men) in the local population influence their body dissatisfaction and weight loss motivations. A higher ratio of women to men in a given population signifies a relative abundance of same-sex mating competitors, intensifying female intrasexual competition. Five studies (N = 1,776) tested the hypotheses that women's perceptions of a female-skewed sex ratio would correspond to increased feelings of intrasexual competitiveness and perceptions of unfavorable mating prospects, which would, in turn, be associated with heightened body dissatisfaction and weight loss motivations. Among university and community women (Studies 1and 2), perceptions of a female-skewed sex ratio corresponded to greater intrasexual competitiveness, increased body dissatisfaction, and increased dieting inclinations. Among single women, assessments of a female-skewed sex ratio corresponded to perceptions of unfavorable mating prospects, increased romantic pressure to alter their appearance, and higher body dissatisfaction (Study 3). Studies 4 and 5 experimentally manipulated perceived sex ratio. Women in the female-skewed condition felt less satisfied with their weights and shapes, but only if they believed the manipulation (Study 4). In Study 5, using a within-subjects design, women who evaluated a male-skewed (vs. female-skewed) dating profile array subsequently desired to lose less weight. Findings suggest women's perceptions of their social environments may contribute to body image and dieting motivations.

RESUMEN

This research differentiated childhood unpredictability (i.e., perceptions of uncertainty or instability due to turbulent environmental changes) from other related constructs to identify its role in adult health. Study 1 (N = 441) showed that, beyond other childhood adversity variables (poverty and adverse childhood experiences or ACEs) and demographic characteristics, perceptions of unpredictability were associated with greater functional disability and worse health-related quality of life (assessed via the CDC's HRQOL Healthy Days measure and the RAND SF-36). Study 2 (N = 564) replicated those findings in a more racially diverse sample and showed that associations with childhood unpredictability held while also controlling for the Big 5 personality traits. Findings suggest that effects of unpredictability were especially pronounced among Hispanic (in Study 1), and Black/African American and low-income participants (in Study 2). Experiencing childhood environments that are perceived to be uncertain, unstable, or uncontrollable may put children on a path toward poor health outcomes in adulthood. Findings advance theories of child adversity and health and identify childhood unpredictability as a potentially valuable target for intervention.

RESUMEN

Guided by principles from life-history theory, theories of adaptive calibration provide an overarching theoretical framework for understanding the developmental roots of impulsivity and externalizing psychopathology. The current research provides evidence for robust associations between perceptions of childhood unpredictability, delay discounting (Studies 1a and 1b), and adult externalizing traits and behaviors (Study 2). Both associations were observed while controlling for perceptions of the harshness of childhood environments, as well as a range of demographic characteristics. The association with externalizing traits and behavior was observed over and above current mood and depressive symptoms. Study 2 also replicated a previously documented association between changes in maternal employment, residence, and cohabitation during childhood and externalizing behavior and, furthermore, suggested that this association was mediated by perceptions of unpredictability. These studies provided no evidence for links between perceived childhood unpredictability and basic forms of risk-taking (Studies 1a and 1c). This research adds to a growing body of work leveraging principles from life-history theory to demonstrate links between childhood experiences, impulsivity, and potentially debilitating forms of mental illness. This work also highlights the value of assessing people's perceptions of their childhood environments.

RESUMEN

Two studies examine psychological and demographic factors that predict attitudes toward mask-wearing during the COVID-19 pandemic. These studies differentiate pro-mask from anti-mask attitudes. Political conservatism, younger age, and gender predicted anti-mask attitudes but were unrelated to pro-mask attitudes. Psychological reactance was associated with anti-mask attitudes, over and above demographic variables. Empathy, trust in healthcare professionals, and perceived normativity of mask wearing were associated with pro-mask attitudes, over and above demographic variables. These studies suggest that demographic variables such as political orientation and age are associated with anti-mask but not pro-mask attitudes, but also that psychological factors differentially predict anti- and pro-mask attitudes over and above demographic factors.
